Size Guide

Reviews Summary
Customers say these training shorts are comfortable, durable, and perfect for various workouts including weightlifting, running, and martial arts. The stretchy material moves well during squats and lunges, while the wide waistband stays secure. Many appreciate the deep pockets and lightweight feel. Common feedback includes praise for the build quality and construction. Some mention the material feels different initially but improves after washing. A few note sizing runs slightly small, particularly in the seat and leg areas, with some recommending ordering a size up. Several customers wish for more color options beyond the current selection.

    Great training shorts!

    Perfect shorts for the gym workout, running, rucking, relaxing and everything in between. Has some stretch for comfort. Great fit, good size pockets. I like the material, it feels durable but yet comfortable.

    simply a superior product

    These are simply excellent for exercise, running, lifting, lounging, etc. I wore them swimming once as well; they worked great. Simply the best exercise / stretchy waistband shorts available. The pockets are large enough to put something in. They are stretchy and durable.

    Ive had these in black for 6 months and they are the favorite shorts I own. They knocked Lululemon off the top of my list. Just purchased the Battleship color for a different look.
